Police said three women were arrested after bringing drugs to Beaverton City Hall then "twerking" -- a dance move involving posterior gyrations made famous by pop singer Miley Cyrus. Then they exposed their genitals, police say, and topped it all off by filming the parking-lot show.

According to Beaverton police, one woman, accompanied by the other two, went into municipal court to pay a fine for a warrant. Then the trio left the building and headed down to the parking lot, where the show began, police said. One lifted her skirt and urinated between two cars, which is when police received a call from a court employee about 3:30 p.m.
